Lucene Developer(s) Apache Software Foundation Stable release 3.4 / September 14, 2011 Development status Active Written in Java Operating system Cross-platform Type Search and index License Apache License 2.0 Website http://lucene.apache.org
Apache Lucene is a free/open source information retrieval software library, originally created in Java by Doug Cutting. It is supported by the Apache Software Foundation and is released under the Apache Software License.
Lucene was originally written by Doug Cutting. It was initially available for download from its home at the SourceForge web site. It joined the Apache Software Foundation’s Jakarta family of open source Java products in September 2001 and became its own top-level Apache project in February 2005. Until recently, it included a number of sub-projects, such as Lucene Java, Droids, Lucene.Net, Lucy, Mahout, Solr, Nutch, Open Relevance Project, PyLucene and Tika. Solr has been merged into the Lucene project itself and Mahout, Nutch and Tika have been moved to be independent top-level projects.
Features and common use
While suitable for any application which requires full text indexing and searching capability, Lucene has been widely recognized  for its utility in the implementation of Internet search engines and local, single-site searching.
At the core of Lucene's logical architecture is the idea of a document containing fields of text. This flexibility allows Lucene's API to be independent of the file format. Text from PDFs, HTML, Microsoft Word, and OpenDocument documents, as well as many others (except images), can all be indexed as long as their textual information can be extracted.
Lucene itself is just an indexing and search library and does not contain crawling and HTML parsing functionality. However, several projects extend Lucene's capability:
- Apache Nutch provides web crawling and HTML parsing
- Apache Solr – an enterprise search server
- ElasticSearch – an enterprise search server.
- Compass – a Java Search Engine Framework
- Hibernate search
- Sphinx (search engine)
- Information extraction
- Text mining
